Facial identification techniques

ABSTRACT

As the use of facial biometrics expands in the commercial and government sectors, the need to ensure that human facial examiners use proper procedures to compare facial imagery will grow. Human examiners have examined fingerprint images for many years such that fingerprint examination processes and techniques have reached a point of general acceptance for both commercial and governmental use. The growing deployment and acceptance of facial recognition can be enhanced and solidified if new methods can be used to assist in ensuring and recording that proper examination processes were performed during the human examination of facial imagery.

RELATED APPLICATION DATA

This application is a Continuation of U.S. patent application Ser. No. 15/838,782, filed Dec. 12, 2017, now U.S. Pat. No. 10,002,288, which is a Continuation of U.S. patent application Ser. No. 15/092,328, filed Apr. 6, 2016, now U.S. Pat. No. 9,881,205, which claims the benefit of and priority under 35 U.S.C. § 119(e) to U.S. Patent Application No. 62/168,351, filed May 29, 2015, entitled “Facial Identification Techniques,” each of which are incorporated herein by reference in their entirety.

BACKGROUND

While both finger and facial images exist as images for processing and comparison, there are key differences between the two:

-   -   Fingerprint images are black and white while facial imagery can         be color or black and white.     -   Fingerprints are caused by touching a surface (which stabilizes         the capture) while facial images are captured with little or no         control over the subject.     -   Finger details (ridge flows and minutia patterns) are a discrete         type of image pattern whereas facial features vary widely across         gender, race, age, hair, pose, lighting, facial obstructions,         etc.     -   There are many accepted courses and career tracks for the         training of fingerprint examiners, whereas there are no current         public courses for the training of facial examiners.

Human examiners can be presented with facial images for comparisons in two distinct ways:

-   -   Computer based algorithms can be used to produce a list of         candidates for review after searching a probe image. This is         referred to as “Facial Recognition” or FR.     -   Two images can be manually selected for review.

In both cases, it is up to the human facial examiner to analyze the two images and produce a final decision whether the person in both images is of the same person. This process has several commonly used definitions:

-   -   Facial Examination (FE): A formal systematic examination of two         facial images to determine if the same person is shown in both         images. An example of this systematic examination technique,         broadly accepted for use in fingerprint examinations, is called         ACE-V (Analysis, Comparison, Evaluation, and Verification).     -   Facial Identification (FI): The human-based examination of the         similarities and differences between two facial images with the         goal of determining if the same person is shown in both.

In any current operational environment using facial biometrics, the act of the FI is where a human facial examiner (or a group of examiners working together) is responsible for making a decision as to whether the same person is shown in two distinct images being compared.

DETAILED DESCRIPTION

Embodiments of systems and methods described herein can operationally ensure that a facial examiner follows specific predefined guidelines or best practices during a facial identification process. While accredited and accepted training for facial examiners evolve, an operational owner can integrate the appropriate guidelines or best practices directly into the actual facial identification processes used in real operational environments or training courses. Such guidelines or best practices can include a list of specific facial components that should be reviewed for every instance of a human facial examiner performing FI.

In one exemplary embodiment, the list of facial components includes, but is not limited to, one or more of skin, face/head outline, face/head composition, hairline or baldness pattern, forehead, eyebrows, eyes, cheeks, nose, ears, mouth, chin or jaw line, neck, facial hair, facial lines, scars, facial marks, and alterations. Other embodiments of the list can include a different set of fewer (or more) facial components. Such guidelines or best practices can also include instructions for each of these facial components to train, assist, or guide the facial examiner when performing the FI for that facial component.

Embodiments of systems and methods described herein directly integrate the list of predefined facial components into the FI process:

-   -   1. Providing a direct on-screen reference to the list of facial         components and their associated anatomical terminology during         the facial review.     -   2. Displaying the areas on the facial components on the face as         defined by the guidelines or best practices.     -   3. Optionally ensuring the facial examiner looks at every facial         component in the list.     -   4. Audit that every facial component in the list is reviewed by         the facial examiner.

Exemplary Steps:

Step 1:

The human facial examiner at a workstation sets the eye locations for both facial images (i.e., probe and candidate images). This operation can be done by manually reviewing and possibly (re)centering the eye locations over the left and right eye locations, as shown in FIG. 1 and FIG. 2 (Image 1 104 and Image 2 204). For example, one or more of the eye locations can be dragged-and-dropped to an updated center location using an input device such as a mouse. This setting of the eye locations is done to create landmarks so that all the facial components to be reviewed can be correlated to the eyes.

Step 2:

After the eye locations for both facial images are reviewed and accepted by the user at the workstation, both images 104 and 204 can be displayed side-by-side, as shown in the exemplary display in FIG. 3.

At this point, two windows 404 and 408 can appear as shown in FIG. 4 that are used during the enforced facial identification process.

-   -   1. In a first window 404 (which can optionally be a standalone         window), any referenced document that the operational owner has         decided to utilize in this facial identification process can be         displayed to the user (i.e., facial examiner). The document can         be placed in at any optimum location within the user's computer         desktop environment.     -   2. The predefined list of the facial components mandated by the         guidelines or best practice is displayed to the user in this         window 404, which can also be placed in an optimum location         within the user's computer desktop environment. In addition to         displaying the list of facial components to be examined, other         information, such as an identification information (ID), viewed         status, and the results of the review can be associated with         each facial component and optionally shown in one or more         windows that can optionally be updated as the steps taken by the         examiner are completed. Table 1 below provides an example of         what may be presented to the user in this second standalone         window.         -   IDs may be associated with the facial components that must             be reviewed; the IDs can enumerate and prioritize the facial             components.         -   The default state of Viewed Status can be NO.         -   The default state of the Results (Similarity/Difference) can             be NULL or empty.

TABLE 1 List of Facial Components Similarity ID Facial Components Viewed (S)/Difference (D) A Skin Y/N S/D/NA B Face/Head Outline Y/N S/D/NA C Face/Head Composition Y/N S/D/NA D Hairline/Baldness Pattern Y/N S/D/NA E Forehead Y/N S/D/NA F Eyebrows Y/N S/D/NA G Eyes Y/N S/D/NA H Cheeks Y/N S/D/NA I Nose Y/N S/D/NA J Ears Y/N S/D/NA K Mouth Y/N S/D/NA L Chin/Jaw line Y/N S/D/NA M Neck Y/N S/D/NA N Facial Hair Y/N S/D/NA O Facial Lines Y/N S/D/NA P Scars Y/N S/D/NA Q Facial Marks Y/N S/D/NA R Alterations Y/N S/D/NA

Step 3:

At this point the user can sequence from facial component A through the last facial component to be examined during the FI process as shown in FIGS. 5-21. In one embodiment, the list of facial components identifies every facial component that must be examined for the FI process to be considered properly performed and in conformance with a particular standard, regulation and/or guideline. As the facial components are sequenced:

-   -   Visual boxes (or other highlighting technique(s)) can be shown         to the user overlaid onto the facial images, which represent the         specific facial component to be reviewed (See FIGS. 5-21);     -   The Viewed column is set from “No” to “Yes”, as the user         examines the facial component—this can optionally be         automatically performed as the user/examiner views each specific         facial component and steps to review the next; and     -   The Similarity/Difference column can be set by the user         indicating whether the specific facial component:         -   shows similarity (S),         -   does not show a similarity (D), or         -   cannot be evaluated (N/A).     -   The referenced guideline or best practice document can         optionally be automatically repositioned to show each specific         facial component within the context of the document.

It is to be understood that the order in which the facial components are examined may differ from that described below. As discussed, FIGS. 5-22 shown exemplary comparisons for various facial features. As illustrated in these exemplary Figures, a visual box(s) and/or highlight is placed around the feature(s) to be compared. Specifically, FIG. 5 shows an exemplary comparison of face/head outlines, with guidelines for the comparison shown in window 404. FIG. 6 shows an exemplary comparison of face/head composition, with guidelines for the comparison shown in window 404. FIG. 7 shows an exemplary comparison of hair/baldness patterns, with guidelines for the comparison shown in window 404. FIG. 8 shows an exemplary comparison of a forehead region, with guidelines for the comparison shown in window 404. FIG. 9 shows an exemplary comparison of eyebrows, with guidelines for the comparison shown in window 404. FIG. 10 shows an exemplary comparison of eyes, with guidelines for the comparison shown in window 404. FIG. 11 shows an exemplary comparison of cheeks, with guidelines for the comparison shown in window 404. FIG. 12 shows an exemplary comparison of noses, with guidelines for the comparison shown in window 404. FIG. 13 shows an exemplary comparison of ears, with guidelines for the comparison shown in window 404. FIG. 14 shows an exemplary comparison of mouths, with guidelines for the comparison shown in window 404. FIG. 15 shows an exemplary comparison of chin/jaw lines, with guidelines for the comparison shown in window 404. FIG. 16 shows an exemplary comparison of neck, with guidelines for the comparison shown in window 404. FIG. 17 shows an exemplary comparison of facial hair, with guidelines for the comparison shown in window 404. FIG. 18 shows an exemplary comparison of facial lines, with guidelines for the comparison shown in window 404. FIG. 19 shows an exemplary comparison of scars, with guidelines for the comparison shown in window 404. FIG. 20 shows an exemplary comparison of facial marks, with guidelines for the comparison shown in window 404. FIG. 21 shows an exemplary comparison of alterations, with guidelines for the comparison shown in window 404.

Step 4:

FIG. 22 shows an exemplary embodiment of embedded synchronized magnifiers 2204 where the eyes can be magnified to assist the user/examiner. These synchronized magnifiers can be moved to any part of the faces and are correlated to show the same portions of the faces 104 and 204 at the same time. FIG. 23 shows an exemplary embodiment of a first increased zoom feature 2304 of the embedded synchronized magnifiers and FIG. 24 shows a second exemplary embodiment of an increased zoom 2404 of embedded synchronized magnifiers. Here, the examiner has zoomed in significantly on one each in each of the probe and candidate images.

As each facial component is displayed to the user, a pair of synchronized magnification areas can optionally be displayed over the images allowing the user to zoom in on any discrete area, as shown, for example, in the above figures. At any time the size and zoom of the magnifiers can be controlled, updated or modified by the user.

Step 5:

In one embodiment, the user cannot complete the facial identification process unless:

-   -   All facial components in the list have been reviewed by the         user; and     -   The user has specified whether for each facial component there         is a similarity, a difference, or it cannot be evaluated.

The user can Exit the facial identification process at any stage in the process, but a decision as to whether the same person is in both images cannot be evaluated in such an event.

At the end of the entire facial identification process, a permanent auditing record may optionally be saved which confirms:

-   -   Two images were reviewed in accordance with a predefined process         (e.g., guidelines or best practices);     -   On a specific date, a user on an operational workstation         performed the facial identification controlled by the predefined         process; and     -   A final decision by the human examiner was arrived at.

FIG. 25 illustrates an exemplary system that can be used in conjunction with the above steps. The exemplary system includes a processor/controller 2504, memory 2508, I/O interface 2512, GPU 2516, facial components database 2520, facial component manager 2524, facial component list manager, verifier and auditor 2528, magnifier module 2532, folder manager 2536, dynamic report generator 2540, audit report module 2544, guidelines 2548, one or more displays 2552, one or more I/O devices 2556, and one or more remote biometric system(s)/databases/back-end systems 2560 (connected via the network(s)).

In operation, and in accordance with one exemplary embodiment, the system can be configured to resemble an email system. While other configurations are certainly possible, the emulation of an email system in terms of workflow at least assists with management and organization of the various images.

In accordance with one exemplary embodiment, the facial component manager 2524, in conjunction with the processor 2504, memory 2508, GPU 2516 and facial components database 2520 present a probe sample to the user at display 2552. This probe sample can be forwarded to a back-end system, such as remote biometric system 2560 to perform initial matching. Once sent, the folder manager 2536 can place the sent probe sample in a “sent folder”— the “sent folder” representing that the probe sample has been sent away for a search to be done by the back-end system 2560. In conjunction with the search being sent out, a demographic filter and/or other filtering criteria can be sent with the image to help reduce the number of false positives received back from the back-end system.

On receipt of the results from the back-end system 2560, an indication can be placed in an “Inbox” by the folder manager 2536 alerting the user/examiner that there are probe and candidate samples ready to review (these results can be stored in the facial components database 2520). The GPU 2516 can provide to the user/examiner, on displays 2552, a candidate screen that shows all candidates returned by the back-end system 2560. This candidate screen, in conjunction with the facial components database 2520 and facial component manager 2524, can be filtered to reduce the number of candidates. For example, a user/examiner can select Yes, No or Maybe, to reduce the number of candidates to a more manageable number with the No candidates optionally being removed from the display.

Next, the user/examiner can perform a detailed review of the probe sample to one or more of the candidates as shown in FIGS. 3-25. During the comparison, the user/examiner can one or more of calibrate the faces, perform a visual alignment of the faces, adjust scaling, adjust colors, and in general adjust any one or more of the characteristics of the probe and candidate sample either in unison or separately. In general any type of image adjustment can be performed including one or more of invert, color channel adjustment, greyscale adjustment, CYMK adjustment, or the like.

As the user/examiner reviews each of the facial characteristics, the facial component list manager, verifier and auditor 2528, in conjunction with the processor 2504, facial component manager 2524 and facial component database 2520, tracks the actions and records the results of the comparisons. The user/examiner during this process can take snapshots of particular features of interest with these snapshots being captured and added into a report which is being dynamically generated by the dynamic report generator 2540. These snapshots can then optionally be supplemented with one or more comments from the user/examiner.

Also, at any time, the guidelines 2548 can be retrieved and displayed to the user/examiner. These guidelines can be dynamically liked to facial features such that if the user/examiner clicks on a particular feature (such as the eyes) the corresponding guidelines (such as in a PDF, text or other document format) for eye comparison can be displayed—such as the guideline shown in FIGS. 10-21 in windows 404.

Optionally, the audit report module 2544 can keep track and store one or more actions taken by the user/examiner, with the stored information usable for one or more of training, to confirm lack of biases, to identify errors and/or to ensure any applicable guidelines have been complied with. This audit trail can then be stored in the facial components database 2520 (or in general at any location and/or printed or sent to a destination such as via email) along with any information about the probe and/or candidate.

Optionally, the dynamic report generator 2540 can generate one or more reports. These reports can be compiled at the end of the review process (e.g., a finalization report) and/or dynamically created as the comparisons are made. As one example shows in FIG. 26, the report 2604 includes one or more sections populated with information regarding comparison decisions that were made. The exemplary sections include: “Snapshot”, “Feature”, “Same/Different”, “Snapshot Images”, “Comments”, and “Data Path.”. Snapshot can indicate a sequence number for the snapshot. Feature can indicate which feature the snapshot is for. Same/Different can represent whether the examiner believes the feature is the same or different. Snapshot images can include images of the comparison. Comments can include any examiner comments and data path can include information regarding the source file for the captured images.

As discussed above, the system can optionally be configured in an email-like manner. Thus, the system can have, for example, a reviewed folder, indicating that the examiner has reviewed and/or completed the comparison. The system can also optionally include a “needs attention” folder for situations where there has been an anomalous error.

For all of the various information, captures, reports etc. described herein, metadata can be associated with that information and can optionally be used for sorting (name, date, ID, etc.) or the like.

FIG. 27 outlines an exemplary method for performing facial recognition. In particular, control begins in step S2704 and continues to step S2708. In step S2708 a probe sample is loaded for display. Next, in step S2712, one or more candidate samples are loaded for display. Then, in Step S2716, the samples can be displayed in a side-by-side or other manner. Control then continues to step S2720.

In step S2720, a predefined list of facial components to be compared is maintained and managed. As discussed, an exemplary embodiment can include one or more of the following facial components that require comparisons: skin, face/head outline, face/head composition, hairline or baldness pattern, forehead, eyebrows, eyes, cheeks, nose, ears, mouth, chin or jaw line, neck, facial hair, facial lines, scars, facial marks, and alterations. Next, in step S2724, the user is guided through the examination process with reference to the predefined list. Then, in step S2728, the user is optionally provided one or more of guidelines/reference material/instructions/examples for the specific comparison being made. Optionally further, the user can have their attention drawn to a specific facial feature being compared. Optionally still, the system can automatically update the display with one or more of the guidelines/reference material/instructions/examples/drawings to correspond to the facial component currently being examined. Control then continues to step S2732.

In step S2732, the predefined list can be updated as each facial component comparison is completed. Next, in step S2736, the user can optionally be required to complete a current comparison before being allowed to proceed to a next comparison. Then, in step S 2740, user actions can optionally be logged as discussed. Control then continues to step S2744.

In step S2744, the user can optionally record one or more of notes/comments/images/comparison results associated with one or more of the comparisons—with one or more of these items optionally being added to a report. Next, in step S2748, the user can optionally be required to perform all comparisons for completion of the facial identification process—with the user optionally being returned to complete any incomplete comparisons. Then, in step S2752 an audit report can optionally be generated. Control then continues to step S2756. In step S2756, a finalization report can be generated with control continuing to step S2760 where the control sequence ends.

In accordance with yet another optional embodiment, the system can include an application that can run on a desktop (e.g., Forensic Spectacles) which allows a user to control and directly push any two images currently displayed anywhere on the desktop directly into a 1:1 examination screen. This allows a user to, for example, see facial expressions—this allows “one click facial review.” In another exemplary embodiment, the linked magnifiers can “snap” examination areas of interest into an off screen repository where they can then be directly published into a finalization document. This allows users to create the final examination report as part of their workflow which can, for example, dramatically shorten the time to create the final report.

In accordance with another exemplary embodiment, the checklist (predefined list) can also lay out the facial components. Another window can optionally be shown that references the correct and accepted anatomical definitions of the facial components. Both the checklist and the definitions can be synced to the facial component the examiner is currently reviewing. This can provide for each facial component 1) a checklist of what to look for, and 2) the proper anatomical terms for the specific component. Therefore, the examiner can be given a full suite of items and proper anatomical definitions for managing the facial identification. FIGS. 28-37 show examples of accepted anatomical definitions of the facial components which are available from fiswg.org—Facial Image Comparison Feature List for Morphological Analysis, which is incorporated herein by reference in its entirety.

Additionally, the following two documents, which are also incorporated herein by reference in their entirety, provide information and background: SWGFAST, Document #10, Standards for Examining Friction Ridge, Impressions and Resulting Conclusions (Latent/Tenprint) at www.swgfast.org/documents/examinations-conclusions/121124_Examinations-Conclusions_2.0.pdf and SWGFAST, Document #8, Standard for the Documentation of Analysis, Comparison, Evaluation, and Verification (ACE-V) at www.swgfast.org/documents/documentation/121124_Standard-Documentation-ACE-V_2.0.pdf.
